I can’t answer your questions directly, but I will say that in Sport mode the throttle control is exceptional. I’ve now owned five bikes with ride-by-wire and ridden a few others. My Ducati has been the only one that I thought was really well sorted. I can now add my SD GT to that list. It may not suit your desire, that is really subjective. But it’s really good

I just got a 17' GT on the 13th of this month. Rolled 1.3k miles today. Fantastic bike. How do you like that top case? Is that the 48 liter? I was considering buying one but holy crap it is expensive.

I like the top case. Yes, it's the 48. Easy on and off. I was disappointed it wasn't keyed to the bike, so now I have separate keys for it. With the torque and the instant response ride by wire throttle, I consider it a requirement for two up riding.
